The Communist Party has selected 2,287 delegates this year for the 19th national congress in Beijing starting October 18.
Attendees will include high-ranking government officials, party leaders, and military officers as well as grassroots members from "frontline production and manufacturing" such as workers, farmers, technicians, nurses and teachers.
According to a circular issued by the Central Committee in November 2016, frontline workers should account for no less than one-third of the delegates.
A total of 771 grassroots delegates have been selected from various social sectors, accounting for 33.7 percent of the total, up by 3.2 percentage points from five years ago, Xinhua reports.
